What happens with this code currently? And are you trying to pre-populate the form with the number of days left, so you can show the price, BEFORE the form is submitted? </p> https://legacy.forums.gravityhelp.com/topic/prorated-dates-question#post-69876 Tue, 07 Aug 2012 11:05:12 +0000 NextFab 69876@https://legacy.forums.gravityhelp.com/ <p>Hello,</p> <p>I am trying to populate the value in the field based on the value entered, in this case date, dynamically. I am trying to calculate prorated dates till the end of the month and based on that to calculate the price.<br /> The problem is, I don't seem to find the way how to make the value appear without the page refreshing. Any workarounds?<br /> I appreciate any help you can give me.<br /> Thanks,<br /> Yulia</p> <p>Here is the code I am starting of:<br /> <pre><code>add_filter(&#39;gform_field_value_prorated_days&#39;, &#39;get_prorated_days&#39;); function get_prorated_days($form){ $start_date = $_POST[&quot;input_5&quot;]; //NOTE: replace 2 with your actual start date input ID $arr = explode(&#39;/&#39;, $start_date); //$end_date = date(&#39;%m/%t/%Y&#39;, strtotime($arr[0].&#39;/01/&#39;.$arr[2])); // $ldom = date(&#39;%t&#39;, strtotime($arr[0].&#39;/01/&#39;.$arr[2])); $end_date = $arr[0].&quot;$ldom&quot;.$arr[2]; $days = gf_date_diff($start_date, $end_date); $arr2 = explode(&#39;|&#39;, $_POST[&quot;input_6&quot;]); $daily_rate = round($arr2[1]/$ldom); $pamt = floatval($daily_rate) * floatval($days); //$_POST[&quot;input_17&quot;] = floatval($daily_rate) * floatval($days); return $pamt; } function gf_date_diff($start, $end) { $start_ts = strtotime($start); $end_ts = strtotime($end); $diff = $end_ts - $start_ts; return round($diff / 86400); }</code></pre>
